The Los Alamos Neutron Science Center (LANSCE) Vacuum System and Superconducting Cavity Research at LANL

概要

I have been working at LANL since May 2000. I was hired as a team leader to test SRF cavities for a project called Accelerator Production of Tritium (APT). Unfortunately, this project stopped in a year or so, then I became a project leader to dismantle an accelerator named Low Energy Demonstration Accelerator (LEDA), a ~100 mA CW ~7 MeV RFQ to accelerate protons. After that, I became a team leader of the vacuum systems team that is in charge of the Los Alamos Neutron Science Center (LANSCE) accelerator (800MeV H+/- accelerator) vacuum systems in 2005. In my talk, I will show the LANSCE vacuum system and what we have done to improve vacuum system of this ~50-year-old accelerator. Also, I have been always interested in the SRF cavity research in my enter career including my work at KEK (1985-2000). Especially, I was very interested in a superconductor MgB2 that was discovered in Japan in 2001 and has a very high Tc of ~40 K as one of possible materials for SRF cavities. I will show some major results on my study on MgB2.
